Question

Show transcribed image textA croquet ball weighing 8.6 N is travelling at 2.3 N. For how long of a time interval must a force of 4.5 N be applied to this object I n order to stop it. 0.270 N 0.449 N 0.876 N 1.125 N 3.742 N a bullet of mass 0.3 g is travelling at 1275 m/s when it embeds into a piece of wood (mass = 18g) which is initially at rest on a frozen lake. Take mu s = mu k = 0.28 for the ice- wood interface. Ignore air resistance. What is the instantaneous velocity of the wooden block after being hit by the bullet? 0.2 m/s 23.3 m/s 357.0 m/s 1275 m/s 20.9 m/s
